Done a few prints with LokBuild and the adhesion is in fact impressive.
Used only PLA for now but I had to completely disable any heating of the bed.
The 1st test with bed at 60˚C was very difficult to remove the finished print.

Anyway, the LokBuild is simply incredible.
The results after a few more prints continue to be always a success, even with some difficult corners or very small footprint.
Adhesion is impressive, with or without heated bed. And the distance to the bed can be a bit higher than usual, it keeps adhering very well.

To remove the parts sometimes I need to use the bladed spatula, with the uaual caution to not scratch the LokBuild, and even so it looks like new without any visible abrasion.

Compared to all the other alternatives that I've tested, it is so much better and simple to use than:
- direct to aluminium;
- kapton tape;
- blue painters tape;
- glass;
- paper glue stick;
- Fleks3D;
- BuildTak.

It seems that after a few years looking for the perfect bed setup, this is it!

It might look like but I do not have any connection at all with the LokBuild company. This is a honest comment of a happy customer.
